Heliophysics

Heliophysics

What causes the Sun to change?How does Earth react to the Sun?How does the Sun affect humanity?

NASA’s heliophysics research investigates the connection between the Sun, the heliosphere, and planetary environments.

As part of NASA’s education and public outreach programs in heliophysics, solar scientists and educators work to dispel the myth that the Sun is an unchanging beacon in our sky. When shared and explained, solar images and research results enlighten curious minds to the Sun’s great intensity and influence over our lives. Understanding the connection between the Sun and Earth helps us appreciate and evaluate the impacts of solar variability on humans, technological systems, and the presence of life itself.
